Abstract

Background: The present study was undertaken to investigate the association of pathological features, including the total tumor volume (TTV), maximum tumor area (MTA), and maximum tumor diameter (MTD), with the local extent of disease in clinically localized prostate cancer. Methods: Serial whole sections of the prostate from 164 patients who underwent radical prostatectomy for localized prostate cancer were investigated. The correlations between the indicators of tumor size, including the TTV, MTA, and MTD, and other pathological parameters were evaluated. Results: The MTD, MTA, and TTV were significantly correlated with each other. Multivariate stepwise logistic regression analysis indicated that the Gleason score, perineural invasion, microvascular invasion, and MTD were significant independent parameters associated with extraprostatic disease. Conclusion: The histological tumor grade, perineural invasion, microvascular invasion, and tumor size were correlated with the local extent of disease. The MTD, a simple, easy, and inexpensive parameter, is a more significant pathological feature associated with the local extent of disease than the MTA or TTV.
